IMPROVEMENT IN I AMP-BURNERS.V

Specitication forming part of Letters Patent No. 176,920, dated May 2,1876; application iiled January 14, 1876.

To all 'whom it mag/concern: y f 7 Be it known that I, ALBERT ANGELL, ofEast Orange, county of Essex and State of New Jersey, 'have invented anew and Improved Lamp-Burner, which improvement is fully set forth inthe following specilication, reference being had to the accompanyingdrawing, in which- Figure l represents a side View. Fig. 2 is a verticalcentral section. Fig. 3 is a horizontal section in the plane :r w, Fig.2. Fig. 4 is vertical section of a modification.

Similar letters indicate corresponding parts.

This invention relates to a lam p-burner with a center draft,vwhichcommunicates with the externall air by a transverse channel openinglinto the outside air-space which surrounds the wick-tube. The inner wallof the outside airspace forms a slide, which can be adjusted up and downby an oblique slot and a pin, so as to increase or diminish the centerdraft, and

to regulate the flame. In the top of the wicktube is fitted an absorbentnon-combustible or refractory ring, which rests upon a filling of cottonor other fibrous material that extends down in the oil-cistern, so thatthe non-co m bustible ring is supplied with oil by the fibrous material,while, by its action, said brous material is protected from being burnedor charred.

ln the drawing, the letter Adesignates the wicktube ot' my burner, theupper portion ot' which is of a'larger diameter than its lower lportion,and which is provided with a screwnipple, a, -to fit a correspondingsocket in the lamp. The upper part of the wick-tube is provided with across-channel, b, which communicates, by an opening, o, with thecenter vdraft d. 0n the outside of the wick-tube is fitted a sleeve, B, which isprovided with a cup, O, for the support of the chimney, and

'with a conical jacket, l), between which and the sleeve B is formed theoutside air-space d',`

to which air is admitted from below through holes e. In the sleeve B areholes f,'which open in the air-space di', and, if said sleeve is moveddown to the position shown in Fig. 2, said holes coincide with4 theopenings of the cross-channel b, and the center draft is in freecommunication with the air-space d.

In the lower part of the sleeve B is cut an oblique slot, g, Fig. l,which catches over a pin, It, projecting from the wick-tube. If thesleeve is turned round, therefore, it is also raised or lowered by theaction of the oblique slot on the pin h, and by turning the sleeve inthe direction of the arrow marked on it in Fig. lit is raised and turnedso that the openings of the cross-channel are gradually closed, and thecenter draft is diminished or entirely shut oft'. At the same time, themouth of the outside air-space is raised above the top edge of thewick-tube, and the ame is reduced or finally put out entirely.

ln the top of the wick-tube is` fitted a ring, E, which is made of anabsorbent and noncombustible or refractory material, such as asbestus,or a mixture ot' asbestus and pumice-stone. This ring bears 011 apacking, F, of cotton or other fibrous material, which eX- tends downthrough the wick-tube into the oilcistern.

If desired, a spring, G, may be introduced, as shown in Fig. 4, to keepthe fibrous material in close contact with the absorbent noncombustiblering E.

By the fibrous material the ring E is kept supplied with oil, and, it'the lamp is lighted,

-said ring protects the fibrous material from being burned or charred.

Iithe ring E should ever become choked up or burned out it can easily beremoved and replaced by another. 4

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the wick-tube A, cross-channel b, center draftd, and pin l1., of a sleeve, B, with air-space d', openings e f, andoblique slot ig, all constructed and operating substantially as shownand described.

.2. The combination, with the Wick-tube A and center draft d, of anabsorbent non-combustible ring, E, and a packing, F, of fibrousmaterial, substantially as set forth.

In testimony that I claim the foregoing I ALBERT ANGELI.. [1.. s]
